Abstract (en)
[origin: WO9420048A1] This is a system for achieving reduction of curvature of the lumbar region of the spine associated with spondylolisthesis that includes a hook assembly (200) attached to vertebra L4, transverse plates (48, 50) attached to vertebrae L4, L5, and sacral plates (52) affixed to opposite sides of the sacrum. The hooks and the plates in combination with the longitudinal plate along the posterior antierior plane in which the spinous processes lie allows for effective reduction of the curvature and secure fixation of this region of the spine. A related system for stabilizing the cervical region of the spine includes transverse plates (248, 252, 254) affixed to vertebrae C3, C4, C5. These plates in combination with a longitudinal plate allow for effective stabilization. The transverse plates include textured surfaces (138) that allow them to mate in a manner which prevents undesirable slippage there between. The system is also compact and does not interfere with the paraspinal muscles which run along either side of the spinal processes.
